Be careful as Crypto as been volatile - Scale in only when the above 2 marking have been breached i.e Candle close above the marked area on Hourly basis.
Scale in partially at point 1 around 3200 level and fully once close happens above 3600 levels.
As you must have seen for the last few days that BTC and ETH have taken a breather. After a long consolidation, ETH is attempting to breakout from its range.
You should only focus on Price Action and check the Daily and Hourly time frame.
The only problem with the breakout is lack of strength i.e Volumes. I would rather miss out an opportunity than preempt
